scenebulider 无法打开 fxml 文件

Question

我正在用 JavaFX 创建一个应用程序。打开 scenebuilder 时收到此错误："Could not open Loggin.fxml. Open operation has failed. Make sure that the chosen file is a valid fxml document."

点击 "Show details"，它显示了这个错误：

Answer 1

问题是SceneBuilder(Scene Builder是8.2.0，2016年5月18日发布)当前版本打开的时候必须首先下载库并打开 fxml file.It 就像一个错误，我会找到 link 和 post 它...

虽然会在下次更新中修复。

此版本的解决方案：

1)首先打开SceneBuilder

2)现在打开你的fxml/fxmlfile/files

Answer 2

确保您已将在 .fxml 文件中导入的库安装到 Scene Builder。
